AW Sge: A new member of SU UMa-type dwarf novae

The dwarf nova AW Sge experienced a rare, bright outburst (14.0mag on by R. Stubbings) on July 11. This object had been suspected to be an SU UMa-type dwarf nova (vsnet-campaign 366). The last reported outburst occurred in 1996 August (magnitude 15.0, Pietz) which was a normal outburst (vsnet-campaign-dn 2). G. Masi succeeded in detecting superhumps and establishing AW Sge is a new member of SU UMa-type dwarf novae (vsnet-campaign-dn 19). From the second observation of G. Masi, the superhump amplitude of 0.4mag and the rough estimated period of 0.07d were reported (vsnet-campaign-dn 32). G. Masi and M. A. Tosti performed astrometry and obtained the result of R.A.= 19h 5m8 37.11s; Delta:+16d 41' 28.8" (vsnet-campaign 374). The data observed by G. Masi are available at: vsnet-campaign-data 22, 23). A rapid fading trend was confirmed during July 18 - 19 (vsnet-campaign-dn 44).
